Seventh in the series of Linuxes that run as screensavers for Microsoft Windows comes Damn Small Screensaver.
This comes as a pair of screensavers, 'DamnSmallLinux-4-4-10' which offers network access and is good for home use, and 'DamnSmallLinux-4-4-10-NoNet' which isolates the unattended computer from the network and so is maybe more suitable in a corporate environment.
Unpack QemuSaver-DamnSmallLinux.zip on a Microsoft Windows system and run its setup program. Then go to the Windows screensaver menu and select the DamnSmallLinux-4-4-10 or DamnSmallLinux-4-4-10-NoNet entry. Then sit back, wait, and enjoy.
To close down the screensaver, either do a KDE shutdown, or press Ctrl-Alt-Del and bring up the Windows Task Manager to do the job.
